Remove banned channel content from search

Currently channels that are banned have their content still showing up in search results. We need to make all banned channel content disappear from search, as we need to keep the content on their page for our records, but hide it from public (or we become complicit in the illegality).

See the attached instance from banned channel - https://www.minds.com/gunmandanniel0

[update]:

I just banned https://www.minds.com/usshop321 but am still seeing stuff from that channel in search searching 'hydrocodone' - https://www.minds.com/newsfeed/global/latest;hashtag=null;query=hydrocodone
